This ported shroud compressor housing is engineered for T3/T4E 60-trim turbocharger builds, giving performance-minded enthusiasts a way to extend compressor map width and push more air into a modified engine before surge becomes a limiting factor. It’s built for tuners and builders chasing wider power bands on street and race applications who need a housing that keeps pace with an aggressive 60-trim wheel. If you’re running or building a T3/T4E-based turbo system and want to maximize flow efficiency, this housing is the right foundation.

Specifications

• Compressor Wheel Trim: 60-trim (T3/T4E)
• Housing Feature: Ported shroud (anti-surge machining)
• A/R Ratio: 0.60
• Compressor Inlet: 4″
• Compressor Outlet: 2″
• Frame Size: T04E

Performance & Application

This housing is purpose-built for T3/T4E 60-trim turbochargers used in modified street and race engines where flow range matters as much as peak output. The ported shroud design incorporates anti-surge machining, allowing the compressor to operate efficiently across a broader range of conditions rather than choking off at the edges of its map. This makes it a strong choice for builders pushing their T3/T4E setup harder than a stock housing was designed to handle. It’s best suited for enthusiasts building or upgrading a T3/T4E turbo system who want more usable flow efficiency out of their existing frame size.
